Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transmitter power is increased to extend transmission range, then communication coverage is improved, but energy consumption increases
Solution Approach 1:
The system performs path determination and power sequencing in advance before actual communication operations. By pre-calculating optimal paths and pre-sequencing component activation, the system avoids energy-wasting trial-and-error transmissions and ensures components are activated only when needed, thus extending transmission range efficiently while minimizing energy consumption.
Solution Approach 2:
The system dynamically adjusts power allocation and component activation sequences based on real-time network conditions, battery status, and communication requirements. This dynamic adaptation allows the system to optimize the balance between transmission range and energy consumption by activating only necessary components at appropriate power levels.
2Reliability
If all components are kept fully functional to ensure immediate responsiveness, then system reliability is improved, but power consumption increases
Solution Approach 1:
The system pre-sequences component activation based on predicted communication needs and pre-determines optimal paths. This allows components to be activated in a controlled sequence only when required, rather than remaining continuously powered, thus maintaining system responsiveness while significantly reducing baseline power consumption.
Solution Approach 2:
The system employs periodic activation of radar and communication components based on predetermined sequences and network activity patterns. By activating components periodically rather than continuously, the system maintains operational reliability while reducing average power consumption to acceptable levels for battery-powered nodes.
3Use of energy by moving object
If component activation is delayed to save power, then energy efficiency is improved, but functional readiness deteriorates
Solution Approach 1:
The system pre-sequences component activation and pre-determines optimal communication paths before actual operations begin. This preliminary preparation ensures that when components need to be activated, they can do so quickly following a predetermined sequence, thus maintaining functional readiness while avoiding continuous operation and improving energy efficiency.
4Ease of operation
If battery-powered nodes are used to improve portability, then deployment flexibility is improved, but operational duration is limited
Solution Approach 1:
The system pre-determines optimal communication paths and pre-sequences component activation patterns based on predicted operational scenarios. This preliminary planning enables battery-powered nodes to operate efficiently by avoiding unnecessary component activation and optimizing power usage along predetermined paths, thus extending operational duration while maintaining deployment flexibility.
Solution Approach 2:
The system dynamically changes operational parameters such as component activation timing, power levels, and communication path selection based on battery status and network conditions. By adapting these parameters in real-time, the system maximizes operational duration of battery-powered nodes while preserving the flexibility benefits of portable deployment.
